Blocking and seepage-proofing technology of leaky well
The invention belongs to the field of seepage-proofing of a leaky well, and particularly relates to a blocking and seepage-proofing technology of the leaky well. The upper part of the leaky well is a quaternary phreatic layer; the lower part of the leaky well is a karst aquifer; steel pipes are put inside the well along the well wall; the steel pipes are welded with the wellhead of the well; a lined high pressure fire hose is fixed on the outer side of the outer wall of the steel pipe with brackets; three paste-separating tapes are sequentially fixed at the lower parts of the steel pipes and between lower sections of the steel pipes and the inner wall of the well from bottom to top; the three paste-separating tapes respectively adopt kelp, a rubber seal and kelp; after 22-26 hours and the kelp and the rubber seal swell, the next step is carried out; the pores between the steel pipes and the inner wall of the well are grouted with the lined high pressure fire hose in a reflective manner till the wellhead is filled. The technology adopts grouting in a reflective manner, and after grouting the slurry is fully solidified between new casing pipes (steel pipes) and old casing pipes and among rocks, so that the purpose of blocking off the quaternary phreatic layer is achieved.
